Why Are Ball Bearings Used in Machines?

Ball Bearings

To answer the question regarding why machines use ball bearings in York, PA, it would help to know what ball bearings are. The short answer is that ball bearings are used to connect two parts or to allow two parts to move in a straight line, relative to the other part. They help reduce friction in the applications. So, if you have an application that has two objects and uses a back and forth type of motion to work, you will produce friction as they rub against each other. 

You can use either sliding elements or rolling elements to produce the action you need. Sliding elements result in more friction which is produced when the elements rub against each other. Rolling elements produce less friction because the parts that touch one another are very small and that’s why they produce less friction. Crowd control is a public security practice where large crowds are managed to prevent the outbreak of crowd crushes, 

Ball bearings have three main parts. They have the balls, of course. But they also have two racetracks. These are shaped like rings. The rings work in tandem with one another. They are the same width, but they have diameters that are different. This is because they work In tandem. The smaller diameter track fits inside of the larger diameter track.  What happens is that the balls sit between the inner and outer track. Then they roll around the bearing which helps applications with high rotational speed produce very low friction.

What Kind of Machines Are They Used In?

Of all of the types of bearings, ball bearings are the most common types of bearings. They are used in many different types of applications because their design is so simple. You can find ball bearings in just about every industry and every type of machinery out there. 

Ball bearings are used in skateboards and cars, bicycles, and farm equipment. You find ball bearings in cars as well. Their simple design and exceptional anti-friction ability make them a very versatile and therefore widely used part of the machinery. 

A ball bearing has three parts. It has two races and balls. The races fit inside one another and the balls sit between them. The races have grooves on one side of each of them. The smaller race has the grooves on the outside and the larger race has the grooves on the inside surface. The larger race fits into another piece of the machinery and is attached to the smooth outside surface.  The smaller race fits onto another piece of the machinery with the smooth surface on the inside. The balls fill in the space between the two rings on the grooved sides. This enables them to roll with a minimum amount of friction. The balls are separated by a cage or a retainer.

How Versatile are They?

Ball bearings can be used in two different types of loads. There are thrust loads and radial loads. The balls are generally what carry the load’s weight. When the bearing rotates, the weight of the load drives how the bearing rotates. 

Radial loads are like pulleys. They put weight on the bearing and the weight creates tension. When the weight is applied, the bearing starts to roll. A thrust load applies the weight differently. Applies the weight at an angle and the entire weight is placed on the bearing. A bar stool has bearings and that is how a thrust load works. You sit on the stool or rotate it and all of the weight of the person sitting on it allows the stool to swivel. This versatility is why ball bearings are used in such a wide variety of applications. 

Are Ball Bearings Perfect?

No, ball bearings are not perfect. As with anything else, one can use them incorrectly. When you purchase certain items, you will notice that they have a maximum weight. Ball bearings are no different. They have a maximum weight depending on their size. If you frequently exceed the maximum weight you can cause the ball bearing to become deformed because you put too much pressure on the small contact area.

But due to their versatility and the fact that they are easily manufactured, they are used in all kinds of products. You will find ball bearings in blenders and skateboards. They are also used in cars, exercise equipment, water pumps, and a myriad of other day-to-day products that you use in your home. 

But they are also in marvels like the Hubble Telescope and other scientific applications, many of which have gone to space. They must stay lubricated, but science has even advanced lubrication techniques which further enhance the use of ball bearings. This increases their lifespan and makes them uniquely preferable to competing mechanical technologies.
